Examples of codec.asn1.ConstraintCollection

codec.asn1.DERDecoder
Implements a collection of {@link Constraint constraints} that can be addedto any {@link ASN1Type ASN1Type}. This class is used by the {@link ASN1AbstractType ASN1AbstractType} in order to manage multipleconstraints. It inherits from ArrayList and simply calls {@link Constraint#constrain constrain} on all objects contained in it upon acall to its own constrain method. @author Volker Roth @version "$Id: ConstraintCollection.java,v 1.2 2000/12/06 17:47:28 vroth Exp $"
